| systolic time intervals | See: electromechanical systole, left ventricular ejection time, preejection period. (05 Mar 2000) |
| discrete time model | <epidemiology> A model in which the system jumps from one state to the next at fixed intervals or timesteps. These difference models are simple to understand but often difficult to analyse; Contrast continuous time models. The parameters in such a model refer to the amount of change over the finite timestep; they are sometimes referred to as finite rates. In a (rather precise) sense, a differential equation is what you eventually get from a difference equation when you let the timestep get smaller and smaller and smaller. (05 Dec 1998) |
| doubling time | <cell biology> The time taken for a cell to complete the cell cycle. (10 Oct 1997) |
| Duke bleeding time test | A bleeding time test in which an incision is made in the earlobe and the time until bleeding stops is measured. (05 Mar 2000) |
| incubation time | <microbiology> The time from the moment of inoculation (exposure) to the development of the clinical manifestations of a particular infectious disease. (13 Nov 1997) |
| inertia time | The interval elapsing between the reception of the stimulus from a nerve and the contraction of the muscle. (05 Mar 2000) |
| intra-atrial conduction time | The total duration of electrical activity of the atria in one cardiac cycle. (05 Mar 2000) |
| Ivy bleeding time test | A bleeding time test in which a sphygmomanometer is inflated to 40 mm Hg around the upper arm, a 5-mm deep incision is made on the flexor surface of the forearm, and the time is measured to cessation of bleeding. (05 Mar 2000) |
| thrombin time | Test of the conversion of fibrinogen to fibrin by thrombin in which clotting time of plasma mixed with a thrombin solution is measured. Time is prolonged by afibrinogenaemia, abnormal fibrinogen, or the presence of inhibitory substances, e.g., fibrin-fibrinogen degradation products, heparin. Reptilase, a thrombin-like enzyme unaffected by the presence of heparin, may be used in place of thrombin. (12 Dec 1998) |
| time | 1. Duration, considered independently of any system of measurement or any employment of terms which designate limited portions thereof. "The time wasteth [i. E. Passes away] night and day." (Chaucer) "I know of no ideas . . . That have a better claim to be accounted simple and original than those of space and time." (Reid) 2. A particular period or part of duration, whether past, present, or future; a point or portion of duration; as, the time was, or has been; the time is, or will be. "God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets." (Heb. I. 1) 3. The period at which any definite event occurred, or person lived; age; period; era; as, the Spanish Armada was destroyed in the time of Queen Elizabeth; often in the plural; as, ancient times; modern times. 4. The duration of one's life; the hours and days which a person has at his disposal. "Believe me, your time is not your own; it belongs to God, to religion, to mankind." (Buckminster) 5. A proper time; a season; an opportunity. "There is . . . A time to every purpose." (Eccl. Iii. 1) "The time of figs was not yet." (Mark xi. 13) 6. Hour of travail, delivery, or parturition. "She was within one month of her time." (Clarendon) 7. Performance or occurrence of an action or event, considered with reference to repetition; addition of a number to itself; repetition; as, to double cloth four times; four times four, or sixteen. "Summers three times eight save one." (Milton) 8. The present life; existence in this world as contrasted with immortal life; definite, as contrasted with infinite, duration. "Till time and sin together cease." (Keble) 9. Tense. 10. The measured duration of sounds; measure; tempo; rate of movement; rhythmical division; as, common or triple time; the musician keeps good time. "Some few lines set unto a solemn time." (Beau. & Fl) Time is often used in the formation of compounds, mostly self-explaining; as, time-battered, time-beguiling, time-consecrated, time-consuming, time-enduring, time-killing, time-sanctioned, time-scorner, time-wasting, time-worn, etc. Absolute time, time irrespective of local standards or epochs; as, all spectators see a lunar eclipse at the same instant of absolute time. Apparent time, the time of day reckoned by the sun, or so that 12 o'clock at the place is the instant of the transit of the sun's center over the meridian. Astronomical time, mean solar time reckoned by counting the hours continuously up to twenty-four from one noon to the next. At times, at distinct intervals of duration; now and then; as, at times he reads, at other times he rides. Civil time, time as reckoned for the purposes of common life in distinct periods, as years, months, days, hours, etc, the latter, among most modern nations, being divided into two series of twelve each, and reckoned, the first series from midnight to noon, the second, from noon to midnight. Common time Apparent time as reckoned from the transit of the sun's center over the meridian. 1. To appoint the time for; to bring, begin, or perform at the proper season or time; as, he timed his appearance rightly. "There is no greater wisdom than well to time the beginnings and onsets of things." (Bacon) 2. To regulate as to time; to accompany, or agree with, in time of movement. "Who overlooked the oars, and timed the stroke." (Addison) "He was a thing of blood, whose every motion Was timed with dying cries." (Shak) 3. To ascertain or record the time, duration, or rate of; as, to time the speed of horses, or hours for workmen. 4. To measure, as in music or harmony. Origin: OE. Time, AS. Tima, akin to tid time, and to Icel. Timi, Dan. Time an hour, Sw. Timme. 58. See Tide. (01 May 1998) |

| time-compensated gain | In ultrasonography, an increase in receiver gain with time to compensate for loss in echo amplitude with depth, usually due to attenuation. Synonym: attenuation compensation, depth compensation, time compensation gain, time-compensated gain, time-varied gain control, time-varied gain. (05 Mar 2000) |
